This field specifies either:
A 10-bit address coded on OA [9:0] when XA (expand address, I2C_CON
-
[8]) is set to 1.
A 7-bit address coded on OA [6:0] when XA (expand address, I2C_CON
-
[8]) is set to 0. In this case, application software must set OA [9:7] bits to
000.
Values after reset is low (all 10 bits).

This field specifies either:
A 10-bit address coded on SA [9:0] when XA (expand address, I2C_CON
-
[8]) is set to 1.
A 7-bit address coded on SA [6:0] when XA (expand address, I2C_CON
-
[8]) is set to 0. In this case, application software must set SA [9:7] bits to
000.
Values after reset are high (all 10 bits).

Prescale sampling clock divider value
This register specifies the internal clocking of the I
I2C_PSC [7−0]: Prescale sampling clock divider value (PSC)
The core uses this 8-bit value to divide the system clock (SCLK) and generate
its own internal sampling clock (ICLK). The core logic is sampled at the clock
rate of the system clock for the module, divided by (PSC+1).
